Code migration guide

thinkScript to Pine Script converter

A thinkScript study usually maps to Pine definitions, ta functions, and plots, while a thinkScript strategy needs its AddOrder simulations and recursive series adapted to Pine strategy commands and execution settings.

Conversion map

What changes between thinkorswim and TradingView

The migration is a model translation. Use this map to decide where the source behavior belongs before writing target syntax.

Source and target platform conversion map
ConcernSource modelTarget modelMigration decision
LifecycleDeclarative expressions are evaluated over chart data; studies, strategies, scans, and watchlist columns have different contexts.Code runs sequentially across chart bars. Realtime behavior depends on script type and calculation settings.Choose when each thinkorswim calculation should run in TradingView; matching syntax alone does not preserve timing.
Market data and historyDefinitions and plots form time series and access prior values with bracket indexing or recursive definitions.Built-in series values such as close carry bar history and use history references such as close[1].Recheck bar indexing, warm-up requirements, timeframe requests, and behavior on an unfinished bar.
Indicators and chart outputStudies use def, plot, painting, and built-in study functions to render chart analysis.indicator(), plot(), drawing objects, alerts, and the ta.* namespace define chart output.Map calculations before recreating plots, labels, colors, and platform-specific drawing objects.
Orders and positionsStrategies use AddOrder to add simulated orders to charts; platform conditional orders are a separate workflow.strategy.* commands create broker-emulator orders for TradingView strategy tests.Define fill timing, sizing, pyramiding or hedging, stops, and position ownership for the target platform.
Native validationPaste into thinkScript Editor, save it as the correct study or strategy, add it to a chart, and inspect plots or the strategy report.Save in Pine Editor, resolve compiler errors, add to a chart, then inspect plots, alerts, and Strategy Tester behavior.Treat generated Pine Script as a draft until it passes the target editor, chart, and backtest workflow.

Code example

Moving-average cross: thinkScript to Pine Script

These fragments show where the same signal starts in each API. They are not complete standalone programs; lifecycle setup, inputs, plots, and order handling still depend on the selected artifact.

thinkScript source fragment
def fast = Average(close, 10);
def slow = Average(close, 20);
plot longSignal = fast crosses above slow;
Pine Script target fragment
//@version=6
indicator("MA cross", overlay = true)
fast = ta.sma(close, 10)
slow = ta.sma(close, 20)
longSignal = ta.crossover(fast, slow)
plot(fast)
plot(slow)

Workflow

A four-step migration path

Keep generation, target-platform validation, and behavior comparison as separate stages.

  1. 1

    Inventory the source behavior

    Separate calculations, plots, alerts, orders, external dependencies, and assumptions in a thinkScript study or strategy definition.

  2. 2

    Choose the target artifact

    Decide whether the result is a Pine Editor indicator or strategy source file. This choice controls lifecycle methods and available APIs.

  3. 3

    Rewrite through target APIs

    Translate state, series, indicators, drawings, and orders into TradingView concepts instead of replacing function names.

  4. 4

    Validate behavior natively

    Save in Pine Editor, resolve compiler errors, add to a chart, then inspect plots, alerts, and Strategy Tester behavior.

Manual decisions

Decisions code replacement cannot make

  • Choose Pine indicator or strategy and preserve only the thinkorswim contexts used by that artifact.
  • Rewrite recursive def expressions and expansion-area behavior using Pine history and persistent state where possible.
  • Map AddOrder, alerts, labels, and painting strategies to separate Pine features instead of one generic replacement.

Limitations

What the draft cannot prove

  • thinkorswim and TradingView do not share one execution, data, or order model, so behavior can change even when both versions compile.
  • Broker, symbol, session, timezone, history, and fill settings can change signals and backtest results on TradingView.
  • Pineify can generate and revise a Pine Script draft, but the target platform remains the authority for compilation, loading, backtesting, and runtime behavior.

Use cases

When this conversion is useful

  • Move a thinkorswim study to a TradingView indicator.
  • Recreate thinkScript simulated entries in Pine Strategy Tester.
  • Adapt plots and alerts while documenting unsupported scan or watchlist context.
